We need not remind the public, that the peculiar phrases of that disease with which the mind of Cobden is so profoundly impregnated, essentially resolve themselves into the _moneymania;_ the leading characteristic of the mental hallucinations with which the patient is tormented, consists in the inveterate habit of reducing all argument into arithmetical quantities; of calculating the value of all truth at some standard rate per pound sterling, of what it might possibly produce as a matter of trade; of confounding syllogisms with ciphers, and lumbering all logic into pounds, shillings, and pence. With diagnostics of disease so unmistakably developed, it would only be exasperation of the symptoms to exhibit remedially in other than the peculiar form which the patient fancies for the kill-or-cure-all draught; and since he has raised the suit, of which he is the self-constituted judge, in which Cocker is pitted against the colonies, we shall even humour the conceit, and try the question with him according to the principles of law and logic, as laid down and reduced by himself into the substantial shape of a _Dr._ and _Cr._ account, balances struck in hard cash, and no mistake. Firstly, to begin with the beginning, which Mr Cobden, with customary confusion of intellect and arrangement, shoots into the midst of his arithmetic. The worthlessness of the colonies is argued upon the figures, which show that, of the total exports of the United Kingdom, but one-third is absorbed by them, whilst two-thirds are taken by foreign markets; therefore it follows, not that the colonial trade is by 50 per cent less important than foreign, but that, relatively, it is not only of no importance at all, but, by all the amount, an absolute prejudice: such, at least, is the rule-of-three logic of the Cobden school, as, viz.:-- "They should, however, consider what the extent of their trade with the colonies was. The whole amount of their trade in 1840 was, exports £.51,000,000; out of that £.16,000,000 was exported to the colonies, including the East Indies; but not one-third of their export trade went to the colonies. Take away £.6,000,000 of this export trade that went to the East Indies, and they had £.10,000,000 of exports to set against the £.5,000,000 or £.6,000,000 annually which was voted from the pockets of the people of this country to support these colonies."
